Abstract: A subsea unit includes a housing containing a dielectric liquid, a first heat generating component and a second heat generating component. The first heat generating component is arranged in thermal connection with the housing and the second heat generating component is arranged at a distance from the housing. A method of cooling heat generating components contained in a housing of a subsea unit is also presented.
